Ericsson POL regulators are implemented by using non-isolated synchronous buck topology shown in Figure 1. During normal operation of a buck power stage, QH and QL are alternatively switched on and ...

The switched-capacitor (SC) techniques enable the design of various filters that can be realized in monolithic integrated circuits from using state-of-art MOS technology. By replacing the noisy ...

My previous column introduced switched-capacitor filters (SCFs) and explained how the capacitors can replace resistors and improve filter accuracy. To find out more about how well SCFs behave, I used ...

In my May blog post, I described the construction of a low-pass filter that used op-amps, capacitors, and resistors. I ignored thermal drift, long-term accuracy, and other characteristics and tested ...

As previously mentioned, the direct-off-line switchmode supply is so called because it takes its power input directly from the ac power lines, without using the rather large low-frequency (60 50 Hz) ...

Last month, we discussed low power factor and how resonance can disrupt facility operations. This month, we'll talk about harmonic filter design and various system parameters that affect filter ...

Not all UPS designs are the same. As a result of cost savings in the very competitive UPS market, some designs may not have the highest level of component reliability. Capacitors are an integral part ...

Underlying concepts of switched-capacitor circuits. IoT power management using a resonant switched-capacitor dc-dc converter or ultra-low-power switched-capacitor voltage regulators. For Part 2, go ...
